Referring now in detail to the drawings in which like referencecharacters indicate like parts. the improved wrapping machine has beenillustrated applied to the wrapping of magazines designated as M" whichare fed to and travel through the machine ilatwise or in a horizontalplane and to which wrappers W are applied as continuous operation. Theparticular disposition of the magazines M as they travel flatwisethrough the machine is governed by the location of the several wrappingelements. In the illustrated embodiment the magazines are carried ontheir backs with their top edges in the lead and their back edges awayfrom and front or open edges toward the front of the machine.

The improved wrapping machine is shown in its entirety in Figures lthrough 4. With r-eference to Figure l, the machine may be divided intotwo general parts, the first, extending in- Wardly from the left, inlet,infeed or leading end of the machine, the preliminary portion containingmagazine infeed opening and inserting parts, and the second-extendingfrom the preliminary portion to the right, outlet, discharge or trailingend of the machine, the main portion containing the wrapper-applying andsealing parts. In addition, the machine has also been divided withreference to Figure 2 into an inner or far side and an outer or nearside. These terms will be employed throughout the description indenoting the positions of the various parts longitudinally andtransversely of the machine.

The several wrapping elements of the improved machine are mounted on aconveyor table or platform I supported in an elevated position on asuitable base. At the infeed, inlet or left end of the machine isprovided a hopper or feeding chute 2 in which the magazines are stackedfor feeding or introduction into the machine. As shown in detail inFigures 5, 6 and 7, the hopper 2 is substantially U-shaped with itsclosed end at the right facing along the table formed as a lia-t rearplate or wall a", the bottom edge of which is spaced above the table.The sides of the hcpper may be formed as inverted U-shaped members, theupper ends of which slope inwardly to facilitate positioning of themagazines. A vertically disposed bar 5 may be adjustably attached to theoutlet face of the plate 3 by which clearance between the surface of thetable and the lower edge of the plate can be varied to accommodatemagazines of different thickness and allow only one magazine at a timeto be withdrawn from the hopper.

At the bottom of the hopper are spaced fixed runners 6 projecting abovethe surface of the table between which travels an inlet or infeedconveyor l, preferably formed as an endless chain or unidirectionalconveyor having spaced upstanding fingers, pins or pushers 8 whichproject sufficiently to successively engage the bottom magazines of thestack and carry them in succession through the opening at the front ofthe hopper. As shown in Figures 1 and 2, the magazines are conveyed orcaused to travel through the wrapping machine by a plurality of endlessor unidirectional conveyors, all of which are preferably adapted to bedriven through suitable chain or belt drives by a single electric motoror other source of supply Si, operated by a switch Sa. Of the severalconveyors the feed chain 1 extends through the first or preliminarystage, phase or portion of the machine and is .carried at either end onsprockets i6, the inner of which is driven.

Attached to the upper face of the conveyor table or platform andextending longitudinally therealong through this first phase is a guiderail Il against which the .back edges of the magazines abut. Spacedalong the machine from the hopper 2 is a slitter or magazine opener I2which may be hingedly attached to the surface of the table and adjustedin height relative to the table through suitable means such as theadjusting screw I3. rThe opening or slitting blade or edge Ill of theopener is offset and projects into or lies in the path of travel of themagazines carried by the conveyor l. By adjusting its height through theadjusting screw I3, the blade may be caused to insert itself between thepages of each magazine and thus open the magazine at any desired level.To ensure both uniform opening and prevent dislodgement of the magazinesduring the opening operation a weighted presser foot I5 may be mountedon the table in advance of the opening blade Ill. As shown, the pressermay be hingedly attached to the surface of the table and is adapted toengage and press against the front of each magazine.

At its outlet or trailing end the opener I2 overlies and engages thedownslanting leading end of a guide rail I6 which is supported inelevated p0- sition above the table and over the path of travel 0f themagazines by brackets li'. After each magazine has been opened its upperportion is transferred from the opener to the elevated guide rail, thelatter then maintaining the magazine in open position.

While it is possible to feed the magazines directly from initial openingto the wrapping stage, the condition of each magazine after the initialopening particularly lends itself to a heretofore tedious oeration.Accordingly, the travel of the magazines prior to the wrapping stage ispreferably made sumcient to provide or encompass an inserter station i8at which maps or other inserts I may be inserted into'the openings inthe magazines, either manually or automatically. Beyond the inserterstation there is preferably provided a second slitter, opener or openingblade or knife I9 which is adapted to insert itself into each magazinebelow the level at which the latter was opened by the opener I2, thusturning back additional pages of each magazine and pocketing the insertbetween these pages and those turned back in the initial opening, Thisopener is adjustable in height by shims or like means 19a and, as in thecase of the first opener, overlies and is adapted to transfer the openor upper portion of the magazine to an elevated guide rail 2i).

Each magazine, containing its insert and open at the desired level, nextenters the main or wrapping stage of the operation. As they enter thisstage the magazines are transferred from the chain conveyor 1, rst to apair of belt conveyors 2l and later to a second or main chain conveyor22, both of which may be driven by the aforementioned motor 9, and thelatter of which carries the magazines to the discharge end of thewrapping machine. As each magazine enters the wrapping stage of themachine it is met by a wrapper W which is fed into the path of themagazines by separate feeding and conveying means. While the wrappersmay be fed into the machine in the same direction as that in which themagazines travel, an opposed feed is employed in the villustratedembodiment. This feed may comprise a feeding table or other suitablehopper or feeding device 23 of conventional type on which a plurality ofwrappers may be stacked and by which the wrappers can be individuallyextracted from the stack and fed to an upwardly inclined or upslantingconveyor 24 underlying the work table I.

As shown in Figures l, 18 and 2l, the wrapper conveyor 24 travels alongin a guidevvay which may be formed by upper guide rods 25 and lowerguide rods 25a, respectively, round and channelshaped and suitablysupported on the frame of the table and spaced to permit iiatwise travelof the wrappers. To ensure proper positioning of the wrappers theirinner or far ends are guided by an L-shaped guide rail 26 and theirouter or near ends are loosely supported on a raised inslantng guiderail 21, the latter causing the wrappers to tend to flow towards andmaintain engagement with the guide rail 26 As in the case of themagazine feed conveyor 1, the wrapper conveyor is preferably formed of apair of spaced chains 218 provided with upslanting pins or pushers 29,spaced to accommodate the individual wrappers. These chains are carriedon sprockets 3|) at either end of the conveyor, the upper or leftsprocket being mounted ona shaft 3| driven through drives by the motor9.

As will hereinafter become apparent it is desirable to score eachwrapper to facilitate the infolding of a vflap between the pages of theassociated magazine at a later stage in the wrapping operation. For thispurpose there is affixed to the underside of the wrapping table adjacentthe upper or discharge end of the wrapperconveyor 24 a scoring devicecomprising a pair of multipointed scoring discs 32 and an opposed doublegrooved roller 33 positioned to engage each wrapper inwardly of itsouter or near end and apply thereto two parallel rows of scorings orperforations 34 corresponding in spacing to the depth or thickness ofthe lower or unopened portions of the magazines.

On arriving at the upper or left end or terminus of the wrapper conveyorthe Wrappers are transferred to an infeed conveyor 35. This conveyorcomprises the aforementioned pair of relatively wide spaced belts 2|carried at either end on .drums or supporting drums and adapted to bearor press thereagainst are a plurality of relatively narrow spacedgripping belts 31 each engaging and driven through the wrapper conveyordriving shaft 3| and arranged in substantially V-disposition by a pairof pulleys 38 and 39. Of these pulleys the former is aixed to the top ofthe table and the latter is weighted to maintain the belts under tensionand in tight engagement with the Wide conveyor belts. With thisarrangement the leading edges of the wrappers are led from the wrapperconveyor 24 onto the gripping or pressure belts 31 and by the latter fedto theconveyor belts 2| and around the left drum 35, in processreversing the direction of travel of the wrappers to coincide with thatof the magazines. As will be evident, the linear speeds of the wrapperconveyor 24, the conveyor belts 2| and the pressure belts 31, as Well asthe magazine infeed or preliminary conveyor 0, must be synchronized tocause each wrapper, as it reaches the upper surface of the wrappingtable to coincide with one of the magazines. This may be accomplished bythe use of a single chain drive 40 running over sprocket gears ofappropriate size affixed tov the drive shafts of the pulleys carryingthe several members and driving this chain drive through suitable drivesand reduction gearing by the motor 9.

As each of the wrappers is fed through a feeding slot 4| extendingtransversely across the table,

it progressively engages the underside or back of each magazine infed bythe conveyor l) until the magazine rests on the wrapper with the backedge of the former substantially on the transverse center line of thelatter and their leading edges substantially in line, thus dividing theexposed or uncovered portions of the wrapper into a rela-l tively wideinner or far flap 42 and a relatively- 6 narrow outer or near iiap 43,the latter being perforated as aforementioned. During this mating stagethe inner or wide fiap is picked up by fold or deflector rods 44. Theserods are of somewhat S-shape and cross over the path of travel of themagazines with the inner ends of the rods at table level and their outerends supported thereabove, thus causing the inner flap to beprogressively folded over the face or upper side ofthe magazine as thelatter travels down the table.

As previously mentioned, the magazines reach the point of joinder withthe wrappers in opened condition by virtue of the supporting rail 29associated with the second slitter knife |9. While the magazine is stillheld open by an extension of this rail, the narrow outer or under flap43 is brought into engagement with a tucker blade 45 of inverted L-shapeand having an upper flange 46 of increasing width slanting downwardlyand '1nwardly from the infeed or left end of the wrapping machine andprojecting over the surface of the table in the path of travel of themagazines. So shaped, the tucker blade is enabled to first upfold andthen infold or tuck the outer flap of the wrapper into the opening inthe magazine over the lower or unopened portion of the latter, theresulting two folds in the flap being along the fold lines provided bythe scorings 34. lower iiap is folded into the magazine the upper orunfolded portion of the magazine slides 01T of or is released by thesupporting rail 20 and closes over the iiap. thus gripping it betweenthe pages of the magazine.

Concurrently with the engagement of the outer flap 43 by the tuckerblade 45 the inner or over flap 42 is engaged adjacent the back edge ofthe magazine by an overfolding blade 41 similar in shape and opposed inopening direction to the tucker blade 45 and attached to the table onthe opposite or far side of the path of travel of the magazine.. Thisoverfolding blade, which succeeds and assists the fold rods 44 inbringing the flap into engagement with the face of the maga-l zine,causes the inner flap to fold snugly over' the back edge of themagazine.

Spaced beyond the tranverse feeding slot 4| is the main conveyor 22which is preferably formed of an endless chain similar to the magazineand wrapper feed conveyors and having somewhat similar upstanding pinsor pushers 48. Assisted by the belt conveyors, this chain conveyor'carries the magazines and their associated wrappers through thewrapping stage to the discharge end of the table. To prevent slippage ofthe magazines relative to their wrappers in the interval or spacebetween the feed and main conveyors there are provided a pair of presserbelts 49, each overlying one of the beltk driven 01T the drive shaft 3|of the wrapper con-` veyor 24 through a suitable belt drive.

In the illustrated embodiment the belt drive from the drive shaft 3|engages a pulley 54 on a shaft 55 to which is anixed the infeed'orleading pulley '56 of the inner rdriving belt 52. At its As thedischarge or trailing end the inner belt runs over a pulley 51 affixedto a shaft 58 to which is also aiixed the trailing or discharge pulley59 0f the other or outer driving belt 53, the leading or infeed end ofwhich is carried by a fixed pulley 6D. Intermediate their leading andtrailing pulleys, the belts are carried by a plurality of idler pulleys6|, hingedly attached to longitudinal and transverse brackets, 62 and63, respectively, mounted on and disposed above the surface of the tableover the path of travel of the magazines. As shown in Figures 13 and 14,the longitudinal positions of the idler pulleys 6I attached to thelongitudinal brackets 62 may be adjusted as desired while the heights ofthe pulleys 51 and 59 at the discharge ends of the belts are madeadjustable by the adjusting screws 64. To maintain the magazines inproper position transversely of the table there are also provided aninner or far guide rail 65 and a partial outer or near guide rail 66,the former aligned with the inner guide rail Il associated with the feedconveyor 1 by which the back edges of the magazines are guided throughthe remainder of the wrapping operation.

Following the overfolding and tucking operations the outer of theconveyor belts 2| ends and the outer portion of the underside of eachmagazine is then supported directly on the table. The magazines thenenter the sealing cycle or phase of the wrapping machine. At the startof this cycle the projecting sealing flap 5| is brought into engagementwith a pasting or gluing device. This device consists of a pasting wheel61 comprising a plurality of discs 68, the peripheries of which areformed in part by gear or other multi-surfaced segments 69. The pastingwheel is mounted on a shaft carried below the surface of the table anddriven through suitable drives and gearing by the motor 9. Immediatelyabove the wheel the table is slotted to enable the multisurfaced wheelB1 to extend therethrough and engage the underside of the sealing nap.Below its shaft the paster depends into an open-topped paste tank orcontainer 1l. In this container the liquid paste or other sealingmaterial is maintained at a substantially uniform level through agravity feed connected to the bottom of the tank through a pipe orconduit 12 and having at its inner or far end a cup or inverteddome-shaped receptacle 13 for receiving a supply bottle 14 in invertedposition.

To ensure adequate contact between the pastecarrying multi-facedsegments 69 of the pasting discs 68 and the sealing flap 5I there ispreferably provided a multi-bladed idler roller 15 which is hingedlyattached to the table above the pasting wheel 66 and adapted by itsweight to press the nap against the pastel', Since the several blades ofthe roller are positioned to interflt between the blades of the pasterthere is provided a stop in the form of a lock screw 16 positioned toengage the roller-supporting arm 11 and limit the downward movement ofthe roller when the machine is not in operation. Another element of thepastel is a wiper in the form of a multitoothed bracket 18 attached tothe side of the tank above the paste level and positioned to remove orwipe excess paste from the pasting discs before they are brought intocontact with the sealing ap.

It will be noted that the multi-faced pasting edges of the pasting discs63 comprise only a seetor and that the remainders of the peripheries ofthe discs are of decreased diameter. The purpose of this dividedperiphery is to limit the application of the paste to that portion ofthe sealing flap intermediate its leading and trailing edges, this beingaccomplished by making the peripheries of the sectors of less lengththan the width of the wrappers. Consequently by synchronizing therevolutions of the pasting wheel 61 with the travel of the main conveyor22 the leading and trailing edges of the pasting segments 69 willcontact the ap 5l within its leading and trailing marginal edges,preventing excess paste from oozing or being forced out of the edges ofthe flap on sealing with consequent detriment to subsequent handling.

The slot in the wrapping table accommodating the pasting device extendstherebeyond to provide an elongated stepped opening or slot 19 forsealing or accommodating the sealing ilap 5l during the sealing step ofthe wrapping operation. This slot is interrupted by a preferablyone-piece underfolding device attached to the table through a bracketand comprising a downfolding blade 8l and an underfolding blade 82arranged in succession. Of these blades the downfolding blade 8| isformed as a substantially V-shaped nger 83 disposed perpendicular to thetable and having a nap-engaging underedge 84 downslanting toward theright from above the level of the flap to below the table. Thus, as itcontacts the downfolding blade in the course of travel or progress ofthe associated magazine along the table, the sealing ap is downfoldedagainst the front edge of the magazine. Beyond the downfolding blade 3lthe under portion of f the ap 5l projecting below the magazine to theinner side of the table to which the adhesive was applied by the paster61, is engaged by the underfolding blade "82. As shown, this blade has atwisted or turned face, starting as a at vertically disposed surface andending as a flat horizontal surface level with the surface of the table.By virtue of its shape the underfolding blade is enabled to fold theprojecting portion of the sealing flap under the magazine until itfinally rests at against the back or underside of the wrapper.

As the front end of each magazine leaves the underfolding device itsunderside is engaged by a relatively wide belt conveyor 85 similar tothe belt conveyors 2|, and its upper side is brought into contact withan over or presser belt 86 of relatively narrow width, As its nameimplies, the presser belt travels on a plurality of pulleys 81 which arehingedly attached to suitable brackets carried by the table and enabledto apply the sealing pressure requisite to4 effectively seal the sealingflap 5I to the back of the wrapper. This pressure is preferably appliedcontinuously to the discharge end of the table.

To prevent wrinkling of the upper side of the wrapper during the pastingand underfolding operations there may be provided a smoothing plate 88hinged at its leading end above the surface of the table and adapted toengage the wrapper adjacent the main conveyor 22 and hold it flatagainst the front of the magazine.

As the magazines sealed in their wrappers are discharged from thewrapping table they drop onto a discharge table 89 disposed normal tothe wrapping table and carrying a discharge belt conveyor 90 by whichthe magazines are carried away from the wrapping table for furtherhandling. As in the case of the several conveyors previously mentioned,the discharge conveyor may be driven through suitable drives by themotion of the machine.

tor 9 and synchronized in speed of the main conveyor 22. l

To facilitate understanding of the invention the heretofore describedoperation of the several parts of the wrapping machine has been showngraphically in Figures 2l and 22, the former being a perspective Viewshowing a succession of magazines M at various steps in the wrappingportion of the machine. Figure 22 illustrates the various conditions orsteps through which the magazines M pass as they travel or progress fromthe leading to the discharge end of the machine. Of the several views inthis'gure, a shows the stack inwhicha plurality of magazines areintroduced into the machine' through the hopper 2. In b the bottommagazine of the stack has been extracted from the hopper -by the feedingconveyor 1. In c the magazine has been opened by the initial openerblade l2. d shows a map or other matter I inserted in the opening in themagazine. In e the magazine has been opened at a lower point by thesecondopening blade I9, pocketing the map between the upper pages. At fthe opened magazine has entered the wrapping stage 'and rests on itswrapper W. In the next stage, g, the outer iiap 43 has been tucked intothe magazine and the inner flap 42 is in pro'c'ess of being overfolded.In the next stage, h,v adhesive has been applied to the sealing flap 5|`by` the' paster 6l. At i the sealing flap is 'in process vof beingunderfolded by the blades 8| and 82, and at y the sealing ap has beensealed against the back of the wrapper and the wrapping is completed.

In the illustrated embodiment of the wrapping machine numerous of theparts are shown as being adjustable, either automatically through theuse of hinged or like mountings, such as those employed for the idlerpulleys 6I carrying the driving belts 52 and 53, or manually throughwith the 4travel radjusting screws or like means, such as provided forthe initial opener I2. With these adjustments it is possible to handlemagazines and the like of varying thickness. It will also be evidentthat magazines varying in other dimensions can be handled readily bycorresponding variations in the spacing or size of the several parts orelements of the machine without 'change in their character or function.While the illustrated embodiment is capable of wrapping magazinescontinuously at a relatively high output the arrangement of its parts issuch that it is also adapted for use with a companion machine arrangedin parallel if a higher output is desired. In such case by reversing thetransverse positions of the o parts on the companion machine andemploying either the same or separate power means to drive the machines,it is possible to operate a pair of machines either separately ortogether in a minimum of space without interfering with the view of theseveral operating stages or impairing the accessibility of the parts ofeither machine.

From the above detailed description it will be apparent that there hasbeen provided an improved wrapping machine for continuously wrapping asuccession of magazines or the like in which the magazines travelthrough the machine flatwise in a straight line throughout the wrappingoperation, thereby simplifying the construc- While illustrated in itsapplication to the wrapping of magazines, it will be understood that themachine is equally adapted to the wrapping of other fiat articles.
